描述 Description

Please note: SKY65623-682LF is being discontinued and is not recommended for new designs. The suggested replacement is SKY65624-682LF

The SKY65623-682LF is a Microwave Monolithic IntegratedCircuit (MMIC) front-end low-noise amplifier (LNA) designed forGlobal Navigation Satellite System (GNSS) radio receiverapplications. The device provides low current consumption,excellent gain, and a superior noise figure (NF). Output matchingcomponents are embedded inside the device. Only one externalinput matching inductor is required.

The SKY65623-682LF is optimized to operate at 1559 to1606 MHz, which makes it ideal forGPS/GLONASS/Galileo/Compass radio receiver applications.

The SKY65623-682LF is fabricated using advanced SiGe BiCMOStechnology. The LNA uses surface-mount technology (SMT) in theform of a 0.8 × 0.8 mm Quad Flat No-Lead (QFN) package, whichallows for a highly manufacturable and low-cost solution.
